Big Bass, Small Box:

CNet says "the deep bass was impressively deep for a sub as small as the PSW111." You need more convincing? At just a tad over a square foot, this is one of the smallest subwoofers you can buy, and with the combined power of Polk subwoofer technology it's also one of the strongest, biggest, deepest subwoofers you'll ever feel.

PSW111 Features:

Heavy-duty MDF construction is designed and engineered for perfect volume, minutely tuned for distortion-free low frequencies, and internally braced and damped to eliminate internal standing waves and other performance-robbing resonances.

This unique configuration uses a specially tuned and directed port to produce maximum bass impact, using your floor as more than just something to stand upon. Downward-firing ports also keep the cabinet's front profile as sleek as possible.

Unique driver materials, speaker geometry and enclosure construction techniques that actually produce cleaner, clearer sound is at the heart of our patented Dynamic Balance process. This process helps the PSW111 perform effortlessly in high stress, big bass situations when you need them most.

PSW Series subwoofers outperform the competition with durable, resonance-free Dynamic Balance driver materials that stay stiff and move fast. so you experience deep, musical low frequencies and thrilling effects with superior system blending.

Our state-of-the-art Klippel distortion analyzer optimizes the woofer's motor structure, voice coil alignment and suspension for smooth, unimpeded movement over a broad spectrum of the lower frequencies to ensure the best, most efficient performance even at extreme listening levels.
